Introducing Chris Masterjohn Lite

Should you care about your omega-6/omega-3 ratio? The short answer is, no, not unless you’re vegan or eat a diet that doesn’t contain liver, egg yolks, and fish.

Nevertheless, blood testing for arachidonic acid, EPA, and DHA levels can be useful and can guide dietary choices to improve the levels of these fatty acids. Still, don’t get caught up in the arachidonic acid-to-EPA ratio. And be mindful about how EPA behaves differently when you are or aren’t taking aspirin.

Tune in for the details!

  1. Thanks a lot for this episode: I was thinking about asking exactly this question.
    So now I’d like to know how much arachidonic acid and DHA most people need per day. And how does that change with inflammation? I wouldn’t want to go to the hassle and expense of getting a lab test for these fatty acids if a dietary analysis could tell me I don’t have enough.
    Also, do I need to worry about too much EPA if I’m just eating fish and not taking fish oil supplements?

      1. Are you saying these fats are essiential….yet NO ONE knows how much we need a day????? We can only guess???
